I'm filing this bug (from a template, mind you) because the ebuild I'm reporting it against failed to build once I removed my /usr/bin/{gcc,cc,c++,c99} binaries. This means that the ebuild is relying on gcc or cc as compiler, while it should use "$(tc-getCC)" so that user choices are respected, and cross-compiling works as intended. This usually comes down to one of these tasks: - use emake CC="$(tc-getCC)" for building, to ovewrite make's CC variable (defaults to "cc", some upstream rewrites it); - the above plus replacing explicit "gcc" (or similar) calls with $(CC) so that the variable is actually respected; - tc-export CC in src_compile before eventual econf. For C++, you'd have to replace CC with CXX everywhere above, of course. If your package is a special case on this, please let me know. Thanks, Diego
src_unpack contains the following: find -name Makefile.in -print0 | \ xargs -0 -n1 sed -i "s:\(^CC = \).*:\1$(tc-getCC):" Maybe not the most elegant way, but as far as I can see, it does its job. False positive?
This is how I made it work locally. xcompile too :) checking for C compiler checking for gcc... gcc checking whether the C compiler (gcc -Os -pipe -march=armv4t -mtune=arm920t -marm -mthumb-interwork -fomit-frame-pointer -I/usr/armv4tl-softfloat-linux-gnueabi/usr/include/ -I/usr/armv4tl-softfloat-linux-gnueabi/include/ -Wa,--noexecstack -D_GNU_SOURCE -L/usr/armv4tl-softfloat-linux-gnueabi/lib -L/usr/armv4tl-softfloat-linux-gnueabi/usr/lib -Wl,-z,noexecstack) works... no configure: error: installation or configuration problem: C compiler cannot create executables. !!!

Right. Patching the Makefile cannot cure configure issues. Should be fixed now (using tc-export).
